This a is really unusual watch band, marked on the clasp 1/20 12 karat gold filled. It's likely from the 50s but is in excellent condition. It's extremely well made, the braiding is careful and the welds are pretty much perfect. There's no wear through of the fairly heavy plating on the front of the braids, and only a little on the back. It's elegant, but it has some weight. Measures 18mm (for lug size) across, 18 cm (7.25") long, so would fit a wrist up to 7.75" with the watch (depending on the size of the watch).
